2.It________that the road will be closed tomorrow for repairs.A. was announcedB. has been announcedC. had been announcedD. would be announced【答案】 B【解析】【分析】本题考查动词的时态和语态。

题干句子中that到句子结束是宾语从句,且从句动词用“will+动词原形”表示将来,由此推断出空白处谓语动词应用现在的某种时态,在所给四个选项中,只有B项正确。

【点评】考查现在完成时的被动语态,其结构是have/has +been +done。

需要注意宾语从句的时态。

主句用现在时,从句所需的任何时态。

4.Located between the 16th and the 18th floor, ______ I call my “home” is more like a “bird's nest”.A. whichB. thatC. whatD. where【答案】 C【解析】【分析】考查主语从句。

5.They lost their way in the forest, and ___ made matters worse was that night began to fall. A. it B. which C. that D. what【答案】 D【解析】【分析】本题中含有一个主语从句what made matters worse,其中的what引导起这个主语从句,同时在主语从句中做主语。

AC两项不能引导主语从句,which在引导名词性从句的时候总是含有疑问的语义,而本句中并没有疑问的语义。

句意:他们在森林里迷路了,情况更糟糕的是天又黑了。

故D正确。

句意:直到下周天气才放晴,这对我们来说是坏消息。

此处是that引导的主语从句,that无实义,只其引导作用,故答案为D。

【点评】主语从句属于名词性从句,在名词性从句中,that无实义,只起连接作用,不做句子成分;if/whether起连接作用,不做句子成分,有实义“是否”。

做题时注意看从句是否少成分。
